Step-by-Step Instructions

Step 1 — Prepare Your Baking Pan

Line a 9×13-inch baking pan with parchment paper, leaving an overhang on two opposite sides for easy removal later. Lightly grease the parchment with non-stick cooking spray or butter to ensure your M M M Marshmallow Dream Bars release cleanly.

Step 2 — Create the Crust

In a medium bowl, combine 2 cups of graham cracker crumbs with ½ cup of melted butter and ¼ cup of granulated sugar. Stir until the mixture is evenly moistened and resembles wet sand.

Press this mixture firmly and evenly into the bottom of your prepared pan. Use the bottom of a flat glass or measuring cup to compact it into a solid, uniform layer.

Step 3 — Bake the Crust

Preheat your oven to 350°F (175°C). Bake the crust for 8–10 minutes, or until the edges are lightly golden and the surface appears set. This pre-baking step helps prevent a soggy bottom in your final M M M Marshmallow Dream Bars.

Step 4 — Melt the Marshmallows and Chocolate

In a large, microwave-safe bowl, combine one 10-ounce bag of mini marshmallows and 2 cups of semi-sweet chocolate chips. Microwave on high in 30-second intervals, stirring thoroughly after each, until the mixture is completely smooth and melted.

For best results, do not overheat. Stop microwasing when just a few lumps remain—the residual heat will melt them as you stir.

Step 5 — Combine and Spread the Filling

Once the marshmallow-chocolate mixture is smooth, quickly fold in 1 cup of crispy rice cereal. Work swiftly before the mixture begins to set.

Immediately pour the filling over your warm, pre-baked crust. Use a greased spatula to spread it into an even layer, working from the center outward.

Step 6 — Add the Topping and Cool

Sprinkle ½ cup of M&M’s candies evenly over the top of the warm marshmallow layer, gently pressing them in so they adhere.

Allow the pan to cool completely at room temperature for at least 2 hours. For faster setting, you can refrigerate the pan for about 1 hour until firm.

Step 7 — Slice and Serve

Once fully set, use the parchment paper overhang to lift the entire block of M M M Marshmallow Dream Bars from the pan. Place it on a cutting board.

Use a sharp knife to slice into bars. For clean cuts, wipe the knife blade clean between slices. Serve immediately or store in an airtight container.

Common Mistakes to Avoid

• Mistake: Using stale marshmallows that don’t melt smoothly. Fix: Always use fresh, soft marshmallows for a perfectly gooey texture in your M M M Marshmallow Dream Bars.
• Mistake: Overheating the marshmallow mixture, causing it to become tough. Fix: Melt marshmallows over low heat, stirring constantly until just smooth.
• Mistake: Pressing the crust too firmly into the pan. Fix: Press the base gently to maintain a crumbly, tender texture that complements the soft topping.
• Mistake: Adding mix-ins like cereal or chocolate when the marshmallow is too hot. Fix: Let the melted marshmallow cool slightly to prevent ingredients from melting or getting soggy.
• Mistake: Not greasing the pan adequately, leading to bars that stick. Fix: Line your pan with parchment paper and grease it lightly for easy removal and clean cuts.
• Mistake: Skipping the cooling step and cutting bars while still warm. Fix: Allow M M M Marshmallow Dream Bars to cool completely at room temperature for neat, defined slices.
• Mistake: Using butter that’s too cold, resulting in a dry, crumbly crust. Fix: Use room-temperature butter to help the crust ingredients bind together properly.
• Mistake: Overmixing the crust, which can make it tough. Fix: Mix just until the ingredients are combined to keep the base light and delicate.

Storing Tips

• Fridge: Store M M M Marshmallow Dream Bars in an airtight container for up to 5 days. Refrigerate promptly to maintain freshness and food safety.
• Freezer: Wrap individual bars tightly in plastic wrap and place in a freezer-safe container for up to 3 months. Thaw in the refrigerator before serving.
